The essence of peptide chemistry lies in the formation of the peptide bond, a covalent linkage that arises from the condensation reaction between the carboxyl group of one amino acid and the amino group of another. This process, when repeated, builds the polypeptide chain. The sequence of these amino acids dictates the peptide's unique three-dimensional structure and, consequently, its biological activity作者：XY Hu—Structure, Folding and Conformation Analysis De novo design of peptide & protein ·Design, synthesis and NMR structure of a rigid cyclic peptide template..
